  You need a specific material shader to do this. Vray like iray has shaders geared to certain material types. This specific material (real) uses a diffraction grating to split light, which is similar to how holograms and oil on water work. It is the top surface to the rear surface differentiation that causes the wavelength of light to change based on the angle of the fabric to the light source and viewers eye. So what this means in terms of shader is that you need a render engine technology that can generate these types of lightwave and surface layer treatments that mirror real world physics at the micron level. In shader talk this will come from the vray ability to load the Nvidea MDL type shader language. And with that the the many different shaders for fabrics.

  And that is where you need to start your search.

  Summarize the above.
  In clo how not to do.
  It is necessary to use an external another render.

  Vad, that's >> perhaps an assumption. See OSL shaders

  Thin film shaders.
